Email is practically free of cost to send but a costly burden on
receivers having to maintain yet another communications channel.
Radicati forecasts the number of messages per day to grow from 56b in
2003to 164b in 2007. The 902m
mailboxes in 2003 received 60 messages/box/day with spam already well
over 90%: The spam burden is ever escalating but yet many businesses and
individuals cannot afford to abandon email.
Anti-spam legislation is largely useless and the opt-out as opposed to
an opt-in requirement only worsens the situation by victims of spam
validating their email address to the spammers!
